Petroleum engineering majors earn the highest mid-career salaries, followed by nuclear engineering majors, according to a new ranking from PayScale.

The research company, which specializes in compensation data, ranked 319 majors at the bachelor level based on how much money graduates in each field are making. The top 25 bachelor-level majors all have mid-career median pay numbers above $100,000, and the vast majority of them are STEM majors.

The data used in PayScale's College Salary Report is from the company’s online compensation survey, which collects user-provided data about jobs, compensation, employer, demographics and educational background. The sample considered for the 2015-2016 College Salary report was 1.4 million college graduates.

PayScale defines early-career employees as those with five years of experience or less, and mid-career employees as those with at least 10 years of experience.
